YES! We tax tobacco and alcohol, states that legalized marijuana have taxes on purchases, we tax gas, we have a toll tax on bridges, some states tax bottled drinks, some states tax sugary foods. Besides we could use the funds for safety classes or for things like roads or wildfire prevention (my state had a wildfire started by a gun club that went out shooting on hot and dry summer a few years ago—and no charges or penalties were given to the shooters). We could also fund research into gun violence with these taxes.
